That has to be the first really interesting thing I've seen this morning! I've never heard of (or seen) such a thing before! Thank you!

I do have to ask, though - why there seems to be more noise on the ground that seeming does "nothing" in this display? Is that a part of it, or was it poor camera work (and there was something going on in the sky we didn't see)? Also - some of this seems like it was working faster than possible (probably just because I have a poor understanding of what was going on)...

Whatever - based on what I saw here, and some images I've seen on google - it definitely seems like a great art!

I will not respond to Arduino help PM's from random forum users; if you have such a question, start a new topic thread.
